ListedOn Sync
Install Sync on your website
Sync publishes approved facts from your ListedOn profile as Schema.org JSON-LD on your own site. It is optional — your listing and portal work without it.
What Sync does
One lightweight async script loads JSON-LD from ListedOn and injects it into your page. It does not track visitors or replace your existing site content. Machines that parse Schema.org can read the same approved name, location, services, and contact details you maintain in the portal.

Platform guides
Practical steps for common site builders — not an exhaustive list of every CMS.
WordPress
- Use Appearance → Theme File Editor, or a header plugin like WPCode or Insert Headers and Footers.
- Paste the sync snippet before the closing </head> tag in header.php (or via the plugin).
- Save and clear any cache plugin, then test from your ListedOn portal.
Wix
- Open Settings → Custom Code in your site dashboard.
- Click "+ Add Custom Code" and paste the snippet.
- Set placement to Head and apply to All Pages.
Squarespace
- Go to Settings → Advanced → Code Injection.
- Paste the code into the Header section.
- Save — changes apply site-wide.
Shopify
- Online Store → Themes → Edit code.
- Open theme.liquid and paste before </head>.
- Save the theme.
Generic HTML
- Open your site's main template or index.html.
- Paste the snippet inside the <head> section.
- Deploy and verify with Test installation in your portal.
After installing
Use Test installation in your portal Sync panel. We check your homepage for the script and valid JSON-LD. If something fails, email the snippet to your developer from the same page.
